Induction motor rotors do not have poles, just the stator. The stator has four poles. Thank you to everyone for catching my error. 4. Silicon Nitride is a ceramic material.

Thus it is the battery which is left for the primary improvement of the vehicle. Other manufacturers will have a hard time catching this type of technology.
